Patented Mar. 11, 1930 UNITED STATES WALTER K. SEPTER, OF DUQUESNE,PENNSYLVANIA WORKHOLDING APPARATUS Appli-cation filed July 21, 1928.

This invention relates to work supports and, while not limited thereto,relates more particularly to work supports for supporting metal slabsand similar heavy metal articles while defects are being chippedtherefrom,vor other work is being done thereon.

Heretofore, it has been customary when chipping or cutting defects fromthe edges of small slabs to have one workman hold the slab while asecond workman cuts out the defects by a power' operated tool. Thisoperation required the time of two workmen, and was also dangerous,since chips would at times fly and injure the workman holding the slaband, at other times, the slab would fall and in]- ure either one or bothof the workmen. `When cutting defects from large slabs the slabs wereusually set on edge and then blocked up by temporary blocks. This lastmethod was also dangerous in that the slabs would sometimes fall andinjure the workmen.

The present invention provides a mechanical support for supporting theslabs while defects are being chipped or cut therefrom,

and, therefore, eliminates the extra Workmen used to hold the smallslabs, and provides an efficient and safe support that is readilyadapted to support all sizes of slabs.

In the drawings- Figure l is a plan view of a support constructed inaccordance with my invention.

Figure 2 is an end view thereof.

Figure 3 is a fragmentary sectional side elevation through the flangesof the apparatus.

Referring more particularly to the drawings, the letter A designates ananvil block which may conveniently be a section of a 0 steel bloom orany other suitable heavy block adapted to form a solid anvil for theslab or other article being worked on.

An inverted U-shaped base member 2 is fitted over said anvil block A,and has each of its vertical side portions 3 provided with a pair ofhorizontally disposed vertically spaced flanges 4 and 5 which areconveniently formed by riveting lengths of angle irons on the portions3.

serial No. 294,419.

The flanges t and 5 are provided with a plurality of alined holes 6 and7, respectively, to receive bars or rods 8. The holes 7, in the lowerflange 5, are of slightly smaller diameter than the holes 6 in the upperflange 4 and the lower ends of the bars or rods 8 are tapered, as at 9,so as to enter and wedge in the holes 7 In operation, one of the bars 8is mounted in the flanges l and 5 on one side of the base member 2 and aslab to be worked on'is positioned on the base, then a second bar 8 ismounted in the flanges 4 and 5, on the other side of the base member andon the opposite side of the slab, so as to hold the slab in up rightposition.

Tf desired, four bars or rods 8 may be used instead of two, as shown, soas to hold the slab more rigid, and in such case, two bars will bepositioned in the flanges on each side of the base, one bar being oneach side of the slab.

While I have shown and described one specific embodiment of myinvention, it will be understood that I do not wish to be limitedthereto since various modifications may be made without departing fromthe scope thereof as defined in the appended claims.

T claiml. A work holder for metal slabs and the like comprising aninverted U-shaped base member, a pair of horizontal vertically spacedflanges extending outwardly from each of the side members of said base,the flanges of each of said pairs of flanges being provided with aseries of vertically alined holes, and a plurality of rods adapted to bemounted in selected ones of said holes to hold the work in asubstantially vertical position.

2. A work holder for metal slabs and the like comprising the combinationwith a relatively rigid heavy anvil block, of an inverted U-shapedmember adapted to be fitted over said anvil block, a pair of horizontalvertically spaced flanges extending outwardlyV from each of the sidemembers of said base, the flanges of each of said'pairs of flanges beingprovided with a series of vertically alined holes, and a plurality ofrods adapted to be mounted in selected ones of said holes to hold thework in a substantially vertical position,

said rods being held against horizontal movement When mounted in saidholes.

3. A Work holder for metal slabs and the like comprising a hase memberhaving a pair of vertically disposed horizontally spaced side walls, apair of horizontal vertically spaced flanges extending` outwardly fromeach of said Walls of said base, the ianges of each of said pairs offlanges being provided with a series of vertically alined holes, and aplurality of rods adapted to be mounted in selected ones of said holesto hold the Work, said rods being held against horizontal move ment whenmounted in said holes.

In testimony whereof, I have hereunto set my hand.
